| Abstract | ||
| The present study was carried out during the growing season, 2010 -2011 from (9/10 – 25/6) in a private orchard in Bab– Al –zubiar region in Basrah, to study the effect exogenous proline application on salinity tolerance of Cordia myxa L. Seedling. The study consisted of (27) treatments combination between (3) concentration of NaCl salt (0, 6, 12) ds m-1, (3) concentration of proline (0, 75, 150) Mg l -1, and (3) replicates. The results showed that the irrigation water salinity was caused a significant effect in all anatomical characters, in the stem and leaves of plants, The result of anatomical characters showed that the treatment of the salinity and spraying the proline caused increased lower and upper epidermis cells (30.11 and 25.56) um.The interaction between 12 ds m-1 salt and 150 Mg l -1 proline treatment increased the thickness of palisade and spongy layers compared with other treatment) 93.75 and 175.80) um. In addition to the results showed enhanced more conductive tissue differentiation and increased in number of vascular bundles in the midrib and produced more and wide xylem vessels and phloem elements in the stem. | ||
